GeForce GTX 465 vs GeForce GTX Titan X

Intro

Compare all of that to the GeForce GTX Titan X, which uses a 28 nm design. nVidia has clocked the core frequency at 1000 MHz. The GDDR5 memory works at a frequency of 1750 MHz on this particular model. It features 3072 SPUs along with 192 Texture Address Units and 96 Rasterization Operator Units.

GeForce GTX 465		200 Watts
GeForce GTX Titan X		250 Watts
	Difference: 50 Watts (25%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX Titan X should be 228% quicker than the GeForce GTX 465 overall, because of its higher data rate. (explain)

GeForce GTX Titan X		336000 MB/sec
GeForce GTX 465		102592 MB/sec
	Difference: 233408 (228%)

Texel Rate

The GeForce GTX Titan X is much (approximately 619%) more effective at anisotropic filtering than the GeForce GTX 465. (explain)

GeForce GTX Titan X		192000 Mtexels/sec
GeForce GTX 465		26708 Mtexels/sec
	Difference: 165292 (619%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan X is the winner, by a large margin. (explain)

GeForce GTX Titan X		96000 Mpixels/sec
GeForce GTX 465		19424 Mpixels/sec
	Difference: 76576 (394%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
